Understanding the BIOS

The Basic Input/Output System (BIOS) is a fundamental piece of software embedded on a computer’s motherboard. It’s the first code that runs when a computer is powered on, performing essential tasks such as:

• Power-On Self-Test (POST): Diagnosing hardware components to ensure they are functioning correctly.
• Hardware Initialization: Initializing and configuring devices like the CPU, memory, storage controllers, and peripherals.
• Boot Loading: Locating and loading the operating system from a storage device.
• Providing a Low-Level Interface: Offering a basic interface for the operating system to interact with hardware.

Because the BIOS is so central to a computer’s operation, updating it can address compatibility issues, improve performance, and add support for new hardware. However, it’s also a potentially risky process that, if interrupted or performed incorrectly, can render the motherboard unusable.

Preparing for the BIOS Update

Before proceeding with the BIOS update, it is crucial to take the necessary precautions to minimize the risk of complications. Here’s a step-by-step guide:

1. Identify Your Motherboard: Verify that you have the correct motherboard model (ASRock 939SLI32-eSATA2). Incorrect BIOS files can severely damage your motherboard.
2. Download the BIOS File: Download the ASRock 939SLI32-eSATA2 BIOS 1.40 file from a trusted source. The original download link is: https://www.techspot.com/drivers/driver/file/information/7746/. An alternative download source can be found by searching reputable driver repositories; ensure the file is specifically for the ASRock 939SLI32-eSATA2 Bios 1.40. Alternative download links (use at your own risk, verify the source’s reputation):

   • https://www.motherboard.cz/mb/asrock/939SLI32-eSATA2.htm (czech site, exercise caution)
3. Prepare a Bootable DOS Drive: Because the update is designed for DOS, you’ll need a bootable DOS environment. This can be achieved using a USB drive or a floppy disk (if your system supports it). There are several tools available online that can create bootable DOS USB drives, such as Rufus or HP USB Disk Storage Format Tool.
4. Copy the BIOS File: Copy the downloaded BIOS file (and any accompanying flashing utility, if provided) to the bootable DOS drive.
5. Backup Your Current BIOS (Optional): If possible, use the BIOS flashing utility to create a backup of your current BIOS. This can be a lifesaver if the update fails.
6. Ensure a Stable Power Supply: It is absolutely critical to have a stable and uninterrupted power supply during the BIOS update process. A power outage or surge during the update can corrupt the BIOS and render the motherboard unusable. Consider using a UPS (Uninterruptible Power Supply) to protect against power fluctuations.
7. Disable Unnecessary Peripherals: Disconnect any unnecessary USB devices or peripherals to minimize the potential for conflicts during the update process.

Flashing the BIOS in DOS

Once you have prepared the bootable DOS drive and copied the necessary files, you can proceed with flashing the BIOS. The exact steps may vary depending on the specific flashing utility provided with the BIOS file, but the general process is as follows:

1. Boot from the DOS Drive: Restart your computer and configure the BIOS to boot from the USB drive or floppy disk you created. You may need to access the BIOS setup menu (usually by pressing DEL, F2, or F12 during startup) to change the boot order.
2. Navigate to the Flashing Utility: Once the computer boots into DOS, navigate to the directory on the USB drive where you copied the BIOS file and flashing utility.
3. Run the Flashing Utility: Execute the flashing utility by typing its name (e.g., AWDFLASH.EXE) and pressing Enter.
4. Follow the On-Screen Instructions: The flashing utility will guide you through the update process. It will typically ask you to specify the BIOS file to be flashed.
5. Verify the BIOS Version: Some flashing utilities will ask you to confirm the current and new BIOS versions before proceeding.
6. Start the Flashing Process: Initiate the flashing process by pressing Enter or following the on-screen prompts.
7. Do Not Interrupt the Process: Crucially, do not interrupt the flashing process under any circumstances. Do not turn off the computer, unplug the power cord, or press any keys until the flashing utility indicates that the process is complete.
8. Restart the Computer: Once the flashing process is complete, the flashing utility will typically instruct you to restart the computer.
9. Enter BIOS Setup: After restarting, enter the BIOS setup menu and load the default settings. This will ensure that the BIOS is properly configured for your system.
10. Verify the Update: Verify that the BIOS update was successful by checking the BIOS version in the BIOS setup menu.

Potential Risks and Troubleshooting

Updating the BIOS is a potentially risky process. If the update is interrupted or performed incorrectly, it can corrupt the BIOS and render the motherboard unusable. Here are some potential risks and troubleshooting tips:

• Power Failure: A power failure during the BIOS update can corrupt the BIOS. Use a UPS to protect against power fluctuations.
• Incorrect BIOS File: Using the wrong BIOS file can damage the motherboard. Ensure that you have downloaded the correct BIOS file for your ASRock 939SLI32-eSATA2 motherboard.
• Interrupted Flashing Process: Interrupting the flashing process can corrupt the BIOS. Do not turn off the computer or press any keys until the flashing utility indicates that the process is complete.
• Corrupted BIOS: If the BIOS becomes corrupted, the computer may not boot. In some cases, it may be possible to recover from a corrupted BIOS using a BIOS recovery tool or by contacting ASRock support.
• Compatibility Issues: In rare cases, a BIOS update may introduce compatibility issues with certain hardware components. If you experience problems after updating the BIOS, you may need to revert to a previous BIOS version or contact ASRock support for assistance.
